Bridge facility for defending geological disasters and construction method
The invention discloses a bridge facility for defending geological disasters and a construction method, and belongs to the technical field of bridges, the bridge facility comprises a plurality of spherical crown lining plates fixedly laid on a bridge body, each spherical crown lining plate comprises a supporting flat plate and an arc-shaped part connected with the supporting flat plate into a whole, and the arc-shaped parts are arranged in the middle of the supporting flat plate; a defending layer is arranged on the spherical crown lining plate, an arc-shaped groove matched with the arc-shaped part is formed in the defending layer, the arc-shaped groove is matched with the arc-shaped part so that a first gap can be formed between the bottom wall of the defending layer and the top wall of the supporting flat plate, and U-shaped first metal dampers are fixedly installed in the first gaps in the two sides of the arc-shaped part; a second gap is formed between every two adjacent defense layers, and a concrete layer is poured in each second gap. The defense layer can swing along the arc-shaped part so as to relieve impact on the bridge body; and through the arrangement of the U-shaped first metal damper, the energy dissipation effect can be further enhanced, and the supporting force on the defense layer is enhanced.
本发明公开了一种防御地质灾害的桥梁设施及施工方法，属于桥梁技术领域，桥梁设施包括若干个固定铺设在桥梁本体上的球冠衬板，所述球冠衬板包括支撑平板以及与支撑平板连接为一体的弧形部，所述弧形部设于支撑平板中部，所述球冠衬板上设置有防御层，所述防御层设有与弧形部配合的弧形槽，所述弧形槽与弧形部配合以使防御层底壁与支撑平板顶壁之间形成第一间隙，所述弧形部两侧的第一间隙内均固定安装有U形的第一金属阻尼器，相邻两个防御层之间设有第二间隙，所述第二间隙内浇筑有混凝土层。本发明防御层能够沿弧形部摆动以缓解对桥梁本体的冲击；通过U形第一金属阻尼器的设置，能够进一步加强耗能作用且加强了对防御层的支撑力。
